Energy-saving LED technology has been in the limelight as the best way to reduce the electricity demands of residential and commercial lighting.
But how safe are LED lights? A vision researcher from Complutense University in Madrid reports that exposure to LED lights can cause irreparable damage to the retinas of the human eye, UPI reports.
The light from LEDs, or light-emitting diodes, comes primarily from the short-wave, high-energy blue and violet end of the visible light spectrum, said Dr. Celia Sánchez-Ramos.

Her comments are based in part on a 2012 study she co-authored, published in the journal Photochemistry and Photobiology. That study found that LED radiation caused significant damage to human retinal pigment epithelial cells in vitro.
This isn't the first time energy-saving lights have come under scrutiny for safety reasons. Compact fluorescent light bulbs, or CFLs, have been criticized for the mercury they contain and for the high levels of ultraviolet (UV) radiation they can emit.
